Unit shutting off on float safety switch. Performed full system tune up which would include drain line for customer. Completely cleared drain line, checked all pressures, amps, and electrical connections and updated critical cool cloud updates. Noticed sweating on the bottom of the unit and high humidity levels in the house. Variable speed motor and dehumidifier seem to be operating properly. Recommended to customer that we install some more returns in the house to lower static pressure airflow. Customer is interested in a quote for returns being cut in. I advise Corey come out to give the most accurate quote and best locations for returns to be installed. Left system working properly at this time.
